Well then. LASIK it is.
You know glasses exist, right?

we used to live malnourished, with stunted growth, women dying in childbirth to bring 8 kids into the world half of whom would die in childhood, with large numbers of men dying before they couldn't afford reading glasses they would need. (my gf was 1 of 5 surviving from 10 born, with horsedrawn transportation and starvation) all that industrialization brought us to much healthier longer lives filled with amenities un…

You know it's interesting to think about who is doing well and who is not thanks to global industrialization. In the last 50 years "we" in the OECD countries simply moved our polluting industry to poor countries, where people have had their anc…
Carbon intensity of GDP, worldwide, fell almost 40% between 1980 and 2021 [1]. (-1.3% CAGR.)
We do offshore toxic industries. But we're also getting better at being less toxic. Environmentalism isn't all a shell game.

#73PFAS is to my generation as leaded gasoline is to the prior generation(s), and asbestos to the ones before them, and so forth from when the first chimneys were put up to spew toxic sludge into our air and rivers at the start of the industrial revolution. There is something so sad, so unworkable, and so deeply troubling about how this kind of thing keeps happening.
I think we're gonna have several asbestos/lead moments in our lifetimes. PFAS, micro plastics, endocrine disruption, I'd also wager marijuana is likely to have its own big tobacco moment eventually, I've heard fruits and vegetables have slowly been losing nutrient density over generations but I have not looked into that yet. There's more nebulous things like the impact of AI or the way we now communicate (or don't co…

The more I see these kinds of sensationalist fearmongering, the more I am content to not give a damn.

#75This is a scare story - the original "research" The Guardian have linked to is an article by Mamavation which is the blog of Leah Segedie who "has a Masters degree from the University of Southern California in Communication Management". Leah found "Indications of PFAS", organic Fluorine, which may or may not be PFAS. Whilst she may not be wrong, as a wearer of contact lenses myself I would like to know the truth.
I hate this kind of garbage research.
Florine can be used in lots of things, without actually checking there is absolutely no way they can claim it's PFAS.

Also adopting asbestos were somewhat reasonable at that time (from thousands years ago to hundred year ago). Leaded gasoline was terrible from the beginning. They don't adopt ethanol for profit.
You’re confusing quite a few things here. Ethanol wasn’t put in gasoline until decades after the lead came out. Ethanol was absolutely added for profit… but much like HFCS, it was about propping up big agribusiness.

"the most extreme of conditions", so I'm not sure why you wouldn't think this includes sports or physical activities.
Can you link to some examples of such frames?

Just kind of amazing.

Higher percentages of ethanol are arguably not worthwhile, but getting rid of MBTE is almost certainly the right choice.
